To all whom 'it may concern:

Be it known that I, GEORGE E. CURTISS,

tors, of which the following is a specification.

My invention relates to improvements in percolators and the objects of my improvement are simplicity and economy in construction with efficiency in operation, especially with reference to provision for an overflow `of the drip cup.

' 1n the accompanying drawing: Figure 1 is a side elevation of the upper part of my percolator, less the liquid Vessel,` the lower end of the fountain-tube being broken off. lFig. 2 is a plan view of the drip plate or liquid distributer. Fig. 3 is a broken out central vertical section of the upper part of my percolator, the fountain tube and its base' being shown in side elevat-ion. Fig. 4 lis a side elevation of the middle portion of the fountain tu-be, showing the perforated centering and supporting cone, and Fig. 5 is a broken view of the overow boss and part of the drip plate, partly in side elevation and partly in central longitudinal section.

A designates the'l vessel for holding the liquid that the codee or other vmaterial is to be infused with. Y

B is the fountain base from which the liquid is forced upwardly through the founbeing in general of any-ordinary construction. At about the middle of the length of the fountain tube there is xed a perforated centering and supporting cone having a flange 7 at its base and perforations 8 between the said flange and contracted neck'9, by means of which neck it is secured to the said tube, the said cone being hollow so that the perforations open into the space between the inside of the said cone and the outside of the said cone and the outside of the said tube. I

The/drip eu or rece tacle for' the ma- 'terial to be in sed pre erably comprises'a finely perforated base 10, which serves as a strainer, and a glass body 11 through which the percolati'ng action may be observed. The body is held to the base by -means of springs or resilient' clips 12 of l' any desired or ordinary construction. lig-A idly fixed at the center of the drip cup base and projecting upwardly therefrom is an overflow tube 13 of somewhat larger diameter than the fountain tube 6. Vithin the mouth or top of the glass body 11 of the drip cupthere is a drip plate or liquid dis- `tributer 14 of any approved construction,

the same having a flanged rim 15 by meansA of which it issupported within the shouldered mouthv of the glass body in any ordinary manner. Rigidly mounted or formed on the central portion ofthe drip plate 14,

is an overflow boss 16, the lower Aend of which is of a size to receive and t the upper end of the overflow tube 13, as shown in `Fig. 3. |The upper end of the said boss is preferably provided with a top 17 having a central opening of a size to receive and fit the upper end of the fountain tube 6. This boss as shown, projects upwardly to a point somewhat higher than the upper edge of the flanged rim 15 of the plate or distributor 14, and the sides of its body are provided- ,with large overflow passages 18. Thisboss is preferably formed integral with the other The drip r1`he fountain base B is'designed. to rest upon the central portion at the bottom of Athe body of the liquid vessel A. vThe position ofthe perforated'centering and sup- -porting'cone on the fountain tube is such that with the parts in place, the whole weight ofthe drip cup, and whatever it carries, is supported by the said cone, the idrip cup being received within the mouth of the vessel A but not resting thereon; all

as shown in Fig. 3. As shown in the said ligure, the si'de wall vof the glass body v11 of 'the'd'rip cup is provided with an inwardly directed annular flange .21, positioned be low the outwardly flaring engaging ends of the springs 12, and resting on and support'- ed byan outwardly direc-ted flange 22 at the upper end of the cylindrical side wall 23 ofthe Vperforated base 10. The springs 12 have their lower ends secured to the said cylindrical side wall 23. Thus it will be noted that the glass body 11 and the base ioo 10 are positively connected so that the same can be lifted asa unit-by grasping the glass body 11 and they will be supported as a unit'from thebase 10 when the latter rests on the flange 7. The said cone, at its base, adjacent the flange 7 is 4of a size .to substantially fill the lower end of the'overfiow.

10 placed within the drip cup to, confine the' p material therein and the cover placed over the distributer, all asvshown in Fig. 3. The liquid forced up through the fountain tube against the inner side of thercoverffalls down into the Iliquid distributer, passes vthrough the holes therein, down through the coffee into the liquid vessel and-so on repeatedly as long as maybe desired. vIf the strainer becomes clogged, or in case an 2 0 excess of liquid/is' forced up through the fountain tube' and the drip cup is filled to I bverflowing, the liquid rises up above the bottom ofthe distributer 14, and in time passes .inwardly through the overiow passages 18 into :the interior of. the over-y flow boss` 16, down through the overflow tube to the supporting cone and then through the perforations 8 and down into the vessel A, whereby it is impossible -to force up more liquid ythan will pass down through the drip cup and overflow tube. The liquid distributer will cut off the coffee or other material ftobe infused and prevent it from rising up above the bottom of the said distributer, hence the overflow passages cannot become stopped up by the said material as might be the case if there was no cut-ofl plate at the top ,of the drip cup. lThe construction is simple and inexpensive. The body of the drip cup extendswithin the mouth of the vessel A so that any leakage between 'the glass body .and flange of the' distributer 14 and also between the said glass' body and the perforated base 10 will pass downwardly into the said vessel. By mounting the overflow tube Aon the bottom of the drip cup and the l Y overflow boss on .the liquid distributer, the

drip cup may be conveniently lled with the material to be infused, vwhich is confined therein by putting the distributer in place.

' I claim as my invention 1. In a percolator having a liquid vessel and a fountain tube, a drip cup fitted to and received within the mouth of the said vessel and having an overflow tube extend'- ing upwardly from its base around the fountain tube, a liquid distributer fitted to the mouth of the said drip cup and having an :overflow boss extending upwardly around the fountain. tube and upper end of the said overflowA tube, the said boss having overiiow passages at a` point above the bottom of the said liquid distributer and a centering cone positioned between the lower end of the said overflow tube and the fountain tube.

2. In a percolator, the combination of a liquid vessel, a drip cup fitted to the upper part of the4 said vessel, an overflow tube xed on and extending upwardly from the bottom of the said drip cup, a liquid dispart of the said drip cup, an overflow boss projecting upwardly from the bottom of the tended upwardly through the said over- `tributer fitted to and covering the upper y said distributer, and a fountaintube ex-v iow tube and boss, the top of the said boss having a central opening fitted to the upper end of the said fountain tube and a centering cone mounted on the said fountain tube and positioned adjacent the lower end of the said overflow tube.

3. In a percolator, a liquid vessel, a drip cup fitted to the upper part of the said vessel and havingfa central overfiow, tube, a liquid distributer fitted to the ymouth of the said drip cup, a fountain tube and base and aperforated centering and'supporting cone mounted on the middle portion of the Asaid fountain tube for receiving the weight of the said drip cup and its contents.
